TECHNICAL FIELD

The present invention relates to an arylethene derivative inhibiting an activity of an estrogen-related receptor gamma (hereinafter, referred to as ERRγ), or a prodrug, solvate, stereoisomer, or pharmaceutically acceptable salt thereof, and a pharmaceutical composition comprising the compound as an active ingredient.

BACKGROUND AT

A hormone receptor which responds to the hormone is required for regulating development, growth or differentiation of cells through change in intracellular gene expression, and is largely classified into a cell membrane receptor and a nuclear receptor. Among them, there is an increasing interest in an orphan nuclear receptor which is the nuclear receptor and of which the binding ligand has not been revealed.

Estrogen-related receptor (ERR) which is one of the orphan nuclear receptors has three types which are ERRα, ERRβ, and ERRγ, and each position to be activated is different.

In particular, ERRγ shows an activity in spinal cords and a central nervous system, and is a nuclear hormone receptor which is a transcriptional regulatory protein involved in glucose biosynthesis in a liver, and has an increased transcriptional activity for itself when bound to a ligand, thereby helping gene expression related to glucose synthesis. That is, ERRγ is directly involved in glucose metabolism.

In addition, ERRγ is a human nuclear receptor protein called NR3B3, and is encoded by a ESRRG gene. ERRγ functions as a constitutive activator in transcription. ERRγ is a member of a nuclear hormone receptor family of a steroid hormone receptor.

An ERRγ protein is known as a main modulator of various genes related to fatty acid oxidation and mitochondria biogenesis in a myocardium, and also known to be involved in glucose production in a liver.

Meanwhile, diabetic retinopathy is a disease developed by occurrence of circulatory failure in a retina which is specific to diabetic patients, and belongs to one of the three major microvascular complications of diabetes together with diabetic neuropathy and diabetic nephropathy. Occurrence of diabetic retinopathy is related to a disease period during which a patient suffers from diabetes, and in the case of the diabetes diagnosed before the age of 30 corresponding to type 1, the diabetic retinopathy occurs in 17% when the disease period is 5 years or less, and in 98% when the disease period is 15 years or more, and among them, worsening proliferative diabetic retinopathy occurs in about 1% when the disease period is 10 years or less, and in 67% when the disease period is 35 years or more. In the case of type 2 diabetes, it is known that the diabetic retinopathy occurs in 29% when the disease period is 5 years or less, and in 78% when the disease period is 15 years or more, and the proliferative diabetic retinopathy occurs in 2% when the disease period is 5 years or less, and in 16% when the disease period is 15 years or more. In a diabetic patient's retina, it is known that vascular change in a capillary such as hypertrophy of a retinal capillary basement membrane, loss of perivascular cells, and occurrence of microaneurysm occurs, and as time passes, retinal neovascularization subsequent to a wide range of capillary nonperfusion may also occur. This diabetic retinopathy is a kind of diabetes complications, but once develops, the progression thereof is difficult to be prevented by glycemic control, and a treatment method specific to retinopathy is demanded.

It has been reported from a recent study that a low molecular organic compound known as GS K5182 which is (Z)-4-(1-(4-(2-(dimethylamino)ethoxy)phenyl)-5-hydroxy-2-phenylpent-1-en-1-yl)phenol functions as a ligand in ERRγ to inhibit the ERRγ activity, thereby showing an anti-diabetes effect such as relieving hyperglycemia and insulin resistance, and a treatment effect of retinopathy.

Development of a new material which significantly inhibits a transcriptional activity of ERRγ as compared with previously reported GSK5182 is demanded.

Meanwhile, anaplastic thyroid cancer (ATC) is one of the most aggressive and deadly cancers known to develop in humans. ATC rapidly metastasizes from a thyroid gland to lungs, bones, focal lymph nodes, and the brain. This is in contrast with the nature of well-differentiated benign thyroid cancer which explains most of the thyroid cancer, and thus, treatment of ATC which is surgery, a radiation therapy, and a chemotherapy alone or in combination thereof has not exhibited an effect on patient survival. As a result, development of a novel treatment method is urgently demanded.

A sodium iodide symporter (NIS) is a plasma membrane glycoprotein which mediates intracellular active inflow of iodine. In the treatment of thyroid cancer, endogenous NIS accepts a wide range of application of a radioiodine therapy in a clinical situation, which is known as an effective treatment method to remove malignant cells with minimal side effects over the years. Low-differentiated cancer cells including ATC cells tend to represent gradual dedifferentiation leading to a decrease in a NIS level. This prevents ATC cells from accumulating iodine in the cells with a high concentration, and accordingly, causes cell resistance to the radioiodine therapy, leading to a poor prognosis. Therefore, there has been many attempts to recover an NIS function from ATC cells, using several methods such as epigenetic regulation using gene transfer, an epigenome-altering drug, and the like, however, no satisfactory result has been obtained so far.

The biological effect of ERRγ has been extensively studied in various disease models (type 2 diabetes mellitus, alcohol-derived oxidative stress, microbial infection by liver damage and gluconeogenesis of the damaged liver, some metabolic diseases such as liver insulin signaling and iron metabolism), however, the role of ERRγ for the NIS function in ATC has not been clearly studied so far. It has been reported from a recent study that a low molecular organic compound known as GSK5182 which is (Z)-4-(1-(4-(2-(dimethylamino)ethoxy)phenyl)-5-hydroxy-2-phenylpent-1-en-1-yl)phenol functions as a ligand in ERRγ to inhibit the ERRγ activity, thereby improving the function of NIS to increase an ATC intracellular radioiodine uptake and finally exhibit an effect of increasing radioiodine treatment. However, when GSK5182 was administered to an ATC mouse tumor model, a radioiodine uptake in the tumor was not increased. Accordingly, development of a new material which may specifically and significantly inhibit ERRγ transcriptional activity as compared with GSK5182, and as a result, cause a radioactive isotope uptake increase from a cellular level to an animal level is demanded.

Since the arylethene derivative according to the present invention may be used in the form of a prodrug, solvate, and pharmaceutically acceptable salt thereof for increasing in vivo absorption or increasing solubility, the prodrug, the solvate, and the pharmaceutically acceptable salt also fall within the scope of the present invention. In addition, since the arylethene derivative has a chiral carbon, the stereoisomer thereof exists, and the stereoisomer also falls within the scope of the present invention.

The arylethene derivative according to the present invention may be prepared by various methods known in the art depending on the kinds of substituents, and as an example thereof, the following Reaction Formulae 1 to 21 are illustrated, and the following preparation methods do not limit a method of preparing the arylethene derivative of the present invention. The specific details will be described in the following Examples 1 to 121. The preparation methods presented in the following Reaction Formulae 1 to 21 are only illustrative, and it is apparent to a person skilled in the art that the preparation methods may be easily modified by a person skilled in the art depending on certain substituents.

In addition, the present invention provides an ERRγ inhibitor composition comprising the arylethene derivative of Chemical Formula 1, or the prodrug, solvate, stereoisomer, or pharmaceutically acceptable salt thereof as an active ingredient.

In addition, the present invention provides a pharmaceutical composition for preventing or treating an ERRγ-mediated disease, comprising the arylethene derivative of Chemical Formula 1, or the prodrug, solvate, stereoisomer, or pharmaceutically acceptable salt thereof as an active ingredient, and further a pharmaceutically acceptable carrier.

As described above, since the arylethene derivative of Chemical Formula 1, or the prodrug, solvate, stereoisomer, or pharmaceutically acceptable salt thereof exhibits a high inhibitory activity to ERRγ, a pharmaceutically acceptable composition comprising them as an active ingredient may be useful for treating or preventing ERRγ-mediated diseases, for example, metabolic diseases such as obesity, diabetes, hyperlipidemia, fatty liver, or atherosclerosis.

In another general aspect, a pharmaceutical composition for preventing or treating retinopathy includes: the arylethene derivative of Chemical Formula 1 which may effectively inhibit an ERRγ activity, or a prodrug, solvate, stereoisomer, or pharmaceutically acceptable salt thereof as an active ingredient.

The “retinopathy” is a disease caused by chronic or acute damage to a retina of an eye. The retinopathy may involve ongoing inflammation and vascular remodeling. In addition, retinopathy also appears as visual manifestation of a systemic disease such as diabetes or hypertension. The kind of retinopathy includes diabetic retinopathy, retinopathy of prematurity (ROP), or the like.

Here, the diabetic retinopathy refers to an eye complication in which decreased visual acuity occurs due to a disorder following a peripheral circulatory disorder caused by diabetes which is a systemic disease. Diabetic retinopathy has no symptoms at the beginning, but as macular invasion occurs, decreased visual acuity appears. Diabetic retinopathy involves various pathological features such as microaneurysm, phlebectasia, retinal hemorrhage, retinal infarction, macular edema, neovascularization, vitreous hemorrhage, traction membrane, or the like, and when these phenomena are observed as ocular fundus symptoms, diabetic retinopathy is diagnosed. The diabetic retinopathy is a disease caused by a complex combination of various symptoms as described above, and it is unclear whether the disease is treated when one of these symptoms is alleviated.

In addition, retinopathy of prematurity is proliferative retinopathy which may occur in premature babies, in particular low birth weight infants. When a premature baby whose retinal blood vessels are not completely formed at birth has failure in angiogenesis process after birth, abnormal fibrovascular proliferation occurs at a border of an angiogenic site and a non-angiogenic site of a retina, whereby the retina is detached, eventually leading to blindness.

[Example 40] Preparation of (E)-5-(4-bromophenyl)-4-phenyl-5-(4-(piperazin-1-yl)phenyl)pent-4-en-1-ol (20a)

Step 1: Preparation of methyl (E)-5-(4-bromophenyl)-4-phenyl-5-(4-(piperazin-1-yl)phenyl)pent-4-enoate (D-2)

Compound D-1 (6 mg, 0.01 mmol) was added to dichloromethane (2 mL), the temperature was lowered to 0° C., and trifluoroacetic acid (0.05 mL, 0.65 mmol) was slowly added thereto. The temperature was raised to room temperature, and stirring was performed for 12 hours. Water and ethyl acetate were further added to the reaction solution and an organic layer was extracted. The organic layer was dried with anhydrous Na₂SO₄ and filtered. The solvent was distilled under reduced pressure to obtain a residue, which was purified using column chromatography, thereby obtaining 5 mg of the desired compound D-2 (99%).

Step 2: Preparation of (E)-5-(4-bromophenyl)-4-phenyl-5-(4-(piperazin-1-yl)phenyl)pent-4-en-1-ol (20a)

7 mg of the desired compound 20a (41%) was obtained by the same process as step 3 of Example 19, using compound D-2.

[Experimental Example 5] Experiment on Anaplastic Thyroid Cancer

1. Materials and Method

1.1. Cells

CAL-62 which is an anaplastic thyroid cancer cell line was purchased from Deutsche Sammlung von Mikroorganismen and Zellkulturen. The cell lines were all maintained in a DMEM medium highly supplemented with 10% FBS, 1% antibiotic-antifungal agent (Hyclone), at 37° C. under the atmosphere of 5% CO₂. A retrovirus from which an enhanced firefly luciferase gene (effluc) is expressed was treated with CAL-62 cells to establish cell lines in which the effluc genes are stably expressed. The thus-established cell lines were referred to as CAL-62/effluc cells.

1.2. ¹²⁵I Uptake Assay

The cells were plated in a 24-well plate for 24 hours, treated with compound 18a, produced into a 100 mM stock solution in DMSO, and stored at −80° C. for 24 hours. After adsorbing a drug-containing medium, the cells were washed with 1 mL of HBSS, and incubated with 500μ of a Hank’ balanced salt solution (HBSS) containing 0.5% bovine serum albumin (bHBSS), 3.7 kBq carrier-free ¹²⁵I (Perkin-Elmer), and 10 μmol/L of sodium iodide (inactive 740 MBq/mmol) at 37° C. for 30 minutes. Thereafter, the cells were washed twice with ice-cold bHBSS, and lysed with 500 μl of 2% sodium dodecyl sulfate (SDS). Radioactivity was measured using a gamma counter (Cobra II; Canberra Packard, Packard Bioscience). The radioactivity of the cells was normalized using a total protein concentration determined by a BCA kit (Pierce Protein Biology).

1.3. ¹²⁵I Uptake Assay Depending on Compound 18a Drug Concentration

The cells were treated with compound 18a at various concentrations (vehicle, 6, 12 uM), and then a ¹²⁵I uptake test was performed as described above.

1.4. ¹²⁵I Uptake Inhibition Assay by KClO₄

The cells were pre-incubated with 300 μM KClO₄ (as a specific inhibitor to NIS) for 30 minutes to inhibit iodine uptake, and then a ¹²⁵I uptake test was performed as described above.

1.5. ¹²⁵I uptake inhibition assay by MAK kinase inhibitor The cells were pre-incubated with PD98059 or U0126 (as a specific inhibitor to MAP kinase) for 30 minutes to inhibit iodine uptake, and then a 125I uptake test was performed as described above.

1.6 Quantitative RT-PCR

Total RNA was separated using Trizol (Invitrogen, Carlsbad, Calif.). Total RNA (2 ug) was reverse-transcribed into cDNA with RevertAid First Strand cDNA Synthesis Kit (Thermo Scientific, Pittsburgh, Pa.). Genes were amplified with a ViiA 7 Real-Time PCR System instrument (Applied Biosystems) using the primer of each target gene and YBR Green PCR master mix (Applied Biosystems, Foster City, Calif.), using a cDNA template. The primer sequence of each target gene is as follows: ERRγ (forward, 5′-CAG ACG CCA GTG GGA GCT A-3′; reverse, 5′-TGG CGA GTC AAG TCC GTT CT-3′), NIS (forward, 5′-TCT AAC CGA TGC TCA CCT CTT CTG-3′; reverse, 5′-AGA TGA TGG CAC CTC CTT GAA CC-3′), and acidic ribosomal protein 36B4 (forward, 5′-CCA CGC TGC TGA ACA TGC T-3′; reverse, 5′-TCG AAC ACC TGC TGG ATG AC-3′). Each target gene was normalized using a 36B4 gene.

1.7. Clonogenic Assay

The cells were plated in a 6-well plate, and allowed to stand for 24 hours. The cells were treated with 12 μM compound 18a for 24 hours, the drug-containing medium was discarded, and the cells were washed twice with PBS. Thereafter, the medium was replaced with DMEM for 6 hours in the presence or absence of 50 μCi ¹³¹I (KIRAMS, Korea). The cells were washed with cold bHBSS, and allowed to stand in a normalized culture medium for a time corresponding to six doublings. Finally, the cells were fixed in a 4% paraformaldehyde (PFA) solution and stained with 0.05% crystal violet. Control colonies having more than 50 cells and ¹³¹I-treated colonies were counted.

1.8. Western Blot

The cells were treated with or without compound 18a for 24 hours, washed twice with cold PBS, and lysed with a RIPA (Roche) buffer containing a complete protease inhibitor cocktail. In the case of cell membrane protein for NIS, samples were prepared using a protein biotinylation kit (EZ-Link™ Sulfo-NHS-Biotin, Thermo Scientific) according to the manufacturer's instruction. Briefly, any one of non-treated cells or treated cells were washed twice with ice-cold PBS/CM (PBS containing 0.1 mM calcium chloride and 1 mM magnesium chloride, pH 7.3), and incubated with EZ link NHS-sulfo-SS-biotin in PBS/CM (1 mg/mL) at 4° C. for 30 minutes. The reaction was quenched by washing twice using cold 100 mM glycine in PBS/CM, and further incubated with 100 mM glycine in PBS/CM at 4° C. for 20 minutes. Thereafter, the cells were constantly shaken at 4° C. for 1 hour, and rapidly washed twice using PBS/CM before being lysed using a RIPA buffer (Roche) containing a protease inhibitor cocktail and a phosphatase inhibitor. The lysate was centrifuged at 16,000 g, at 4° C. for 30 minutes. A portion of the supernatant was used for a total cell protein immune blot. The remaining sample was incubated with 100 μL streptavidin beads (Thermo Scientific) at room temperature for 1 hour to be used for obtaining membrane protein. The beads were washed three times using a RIPA buffer, the bound protein was eluted using 50 μL of Laemmli buffer (62.5M Tris, pH 6.8; 20% glycerol; 2% SDS; 5% b-mercaptoethanol; and 0.01% bromophenol blue) at room temperature for 30 minutes. Equivalent amounts of the total cell membrane protein and biotinylated cell membrane protein were loaded on each lane, and resolved by a Bis-Tris gel (Invitrogen) with a 4-12% slope. The protein was moved to a 0.2 μm PVDF membrane (Invitrogen). The membrane was incubated with a primary rat monoclonal human NIS-specific antibody (dilution 1:1000, Thermo Scientific, Catalog#: MS-1653-P1, clone: FP5A), and then incubated with a HRP-conjugated secondary antibody at room temperature. ECL-Plus (Amersham Pharmacia) was used for detecting a peroxidase activity, depending on the manufacturer's method. Similarly, even in the case of other protein, an equivalent amount of protein was loaded to each lane, and resolved by a Bis-Tris gel (Invitrogen) with a 4-12% slope. The protein was moved to a 0.2 μm PVDF membrane (Invitrogen). The membrane was incubated with a primary antibody (ERRγ, pERK1/2, β-actin) at 4° C. for one night, and then incubated with an appropriate HRP-conjugated secondary antibody at room temperature. According to the manufacturer's protocol, the peroxidase activity was detected using ECL-Plus. A band density was determined using an ImageJ software.

1.9. Animal Experiment

Nude mice (Balb/c nu/nu, female, 6 weeks old) were used, and all animals were normally raised in DMRC center animal laboratory of Kyungbuk National University Hospital in Chilgok. 5×10⁶ CAL-62/effluc cells were subcutaneously injected into the left femoral region of the nude mouse to form a tumor. The tumor was extracted, divided into small pieces (20 mg or more), and then intradermally injected into the nude mouse to form a tumor.

After forming the tumor, the CAL-62/effluc mouse tumor model was divided into the following groups: Group 1: vehicle, Group 2: 100 mpk compound 18a, Group 3: 100 mpk compound 18a. To the mice of each group, the vehicle (100% PEG) and compound 18a (100 mpk, 200 mpk) were orally administered daily for 6 days. In order to observe a difference in tumor growth between before administration and after administration, optical imaging (bioluminescent imaging) was performed. While the drug was administered, a weight change of the mouse was observed every other day.

In addition, in order to confirm a change in a 125I uptake increase in the CAL-62/effluc tumor, an organ distribution study (Bio-distribution study) was performed as follows. After finally administrating the drug, ¹²⁵I (5 uCi/mouse) was administered to the mouse by intravenous injection on the next day. After 4 hours of administration, all organs including a parent tumor were extracted, and each organ was weighed. Thereafter, each organ was transferred to a 5 mL test tube, and radioactivity in the organ was measured using a gamma counter. A ¹²⁵I uptake degree in the organ was expressed by percentage injected dose per gram (% ID/g).

1.10. Animal Image

For obtaining an optical image, D-luciferin (3 mg/mouse) was intraperitoneally injected to the mouse. After about 10 minutes of injection, the mouse was anesthetized by inhalation (I-2% isoflurane gas), and then positioned on a IVIS Lumina III (PerkinElmer) imaging bed. The time for obtaining the image was automatically set, and then an optical image was obtained. A Living imaging software (version 2.12, PerkinElmer) was used to quantify an optical image signal from the tumor.

1.11. Statistical Analysis

All data was represented as an average ±, and statistical significance was determined using a Student test of GraphPad Prism 5. A P value <0.05 was regarded as being statistically significant.

2. Results

2.1 Increased Radioactive Iodine Uptake in ATC Cells by Compound 18a

After treatment with compound 18a, a significant increase of radioactive iodine uptake in CAL62 cells was confirmed for each concentration and each time (FIGS. 1 and 2). A maximum increase of iodine uptake was observed at a concentration of 12 uM of compound 18a. In order to test whether the increased radioactive iodine uptake is related to regulation of a NIS function by compound 18a, KClO₄ which is an inhibitor specific to NIS was co-incubated with compound 18a-treated CAL62 cells, and a change in a radioactive iodine uptake level was observed. KClO₄ completely blocks radioactive iodine uptake which was increased in the compound 18a-treated cells (FIG. 3), which implies that the increased iodine uptake is directly related to the improved functional activity of NIS mediated by compound 18a.

2.2 Endogenous ERRγ and NIS mRNA Expression Regulation by Compound 18a in ATC Cells

In order to determine the effect of compound 18a on an ERRγ mRNA level in ATC cells, real-time PCR was performed using ERRγ- and NIS-specific primers. As a result of treatment with compound 18a, it was confirmed that ERRγ mRNA expression in CAL62 cells were significantly decreased (FIG. 4), and when compared with the vehicle treated group, the expression was decreased by about 16 times. However, it was confirmed that NIS mRNA expression was increased by about 2 times when compared with the vehicle-treated group.

2.3 Endogenous ERRγ Protein Regulation by Compound 18a in ATC Cells

In order to determine the effect of compound 18a on an ERRγ protein level in ATC cells, immune blotting assay was performed using ERRγ-specific antibody. As a result of treatment with compound 18a, it was confirmed that ERRγ protein expression in CAL62 cells were significantly decreased (FIG. 6), and when compared with the vehicle treated group, the expression was decreased by about 2.8 times (FIG. 7).

2.4 Increase of Membrane-Localized NIS Protein in ATC Cells Through Activation of Endogenous MPA Kinase Signaling by Compound 18a in ATC Cells

A significant increase in a phosphorylated MPP kinase level such as p44 and p42 ERK was found in ATC cells treated with compound 18a (FIG. 8). The relative increase of the phosphorylated forms oERK1 and ERK2f was 2.2 times and 2.8 times, respectively (FIG. 9).

The radioactive iodine uptake increase (FIGS. 10 and 11) and the relative increase of the phosphorylated form of ERK1 and ERK2 by compound 18a were completely inhibited by selective MEK inhibitors, PD98059 and U0126 (FIGS. 12 and 13).

In order to determine the effect of compound 18a on an ERRγ protein level in ATC cells, immune blotting assay was performed using NIC-specific antibody. As a result of treatment with compound 18a, it was confirmed that total NIS protein (fully or partially glycosylated form) expression in CAL62 cells were significantly increased (FIGS. 14 and 15), and when compared with the vehicle treated group, the expression was decreased by about 1.9 times. In order to determine the effect of compound 18a on the state of NIS membrane protein, a change in a level of membranous total NIS protein collected from compound 18a-treated CAL 62 cells using a cell membrane biotinylated kit was examined using an immune blotting examination using an NIS-specific antibody. Compound 18a derived a sharp increase in cell membrane-localized NIS protein having mature and immature forms in ATC cells, as compared with control cells (FIG. 14). Qualitative analysis of band intensity showed increases in membrane fully glycosylated and partially glycosylated NIS protein in CAL62 cells by 8.1 times and 6.4 times, respectively (FIG. 15).

2.5 Modification of I-131 Mediated Cytotoxicity by Compound 18a in ATC Cells

A clone formation assay using I-131 showed a minimal cytotoxic effect in CAL62 cells treated with any one of compounds 18a and I-131 alone (FIG. 16). Relative colony formability of I-131 or GSK5182 group was 92.9±5.8% and 94.5±10.8%, respectively in CAL62 cells (FIG. 17). However, as a result of combining ¹³¹I and GSK5182, colony-formability was significantly decreased to about 58.5±7.4% in CAL-62 (FIG. 17).

2.6 Increase of Radioactive Iodine Uptake by Administration of Compound 18a in ATC Tumor Model

The CAL62-effluc mouse tumor model was divided into the following groups (FIG. 18, Group 1: vehicle, Group 2: 100 mpk compound 18a, Group 3: 200 mpk compound 18a). To the mice of each group, the vehicle (100% PEG) and compound 18a (100 mpk, 200 mpk) were orally administered daily for 6 days. In order to observe a difference in tumor growth between before administration and after administration, optical imaging (bioluminescent imaging) was performed. After finally administering the drug, a radioactive isotope (I-125) was administered to the mice on the next day, and after 2 hours, the mice were sacrificed, all organs thereof were extracted, and a radiation level was measured with a gamma counter. It was confirmed that radioactive iodine uptake in CAL62 tumor was concentration-dependently increased by treatment with compound 18a (FIG. 19). When compared with the vehicle group, the radioactive uptake was increased by 4.4 times and 16.2 times in the 100 mpk and 200 mpk compound 18a groups, respectively. When observing the difference in tumor growth using optical imaging, significant tumor growth inhibitory efficiency was shown in the compound 18a group (FIG. 20). Drug concentration-dependent tumor growth inhibitory efficiency was shown (FIG. 21). An abrupt weight change in the mice was not shown in all groups (FIG. 22).
